One Suspect in Boston Bombing Is Dead One Boston Bombing Suspect Is Dead, Second at Large; Area on Lockdown
(35 minutes later)
BOSTON — The two suspects in the Boston Marathon bombings led police on a wild and deadly chase through the suburbs here early Friday morning that ended in the death of one of the suspects as well as a campus police officer; the other suspect remained at large while hundreds of police officers conduct a manhunt through Watertown, about five miles west of downtown Boston. BOSTON — One of the suspects in the Boston Marathon bombings was killed early Friday morning after leading the police on a wild chase that resulted in the death of a campus police officer, while the other was sought in a massive manhunt that shut down large parts of the area. And Gov. Deval Patrick of Massachusetts said residents of Boston and its neighboring communities should “stay indoors, with their doors locked.”
The surviving suspect was identified as Dzhokhar A. Tsarnaev, 19, of Cambridge, Mass., a law enforcement official said. The suspect who was killed was identified as his brother, Tamerlan Tsarnaev, 26, the law enforcement official said. Investigators believe that both of the suspects were Chechens. The two suspects were identified by law enforcement officials as brothers from Chechnya. The surviving suspect was identified as Dzhokhar A. Tsarnaev, 19, of Cambridge, Mass., a law enforcement official said. The one who was killed was identified as his brother, Tamerlan Tsarnaev, 26.
The Boston region was in the grip of a security emergency as hundreds of police officers conducted a manhunt through the normally tranquil Boston suburbs. The manhunt for the surviving bombing suspect sent the Boston region into the grip of a security emergency: residents of the city and the surrounding area were urged to stay indoors, as hundreds of police officers conducted a manhunt and all public transit services was suspended.
Gov. Deval Patrick has suspended service on all public transit services in the MBTA system in Boston, including the “T” subway, buses and commuter trains. The authorities asked all residents of the towns of Watertown, Newton, Waltham and Cambridge to stay home and stay indoors. Watertown was locked down early Friday morning, with no one allowed to leave their homes and no businesses allowed to open. Col. Tim Alben of the Massachusetts State Police said investigators believed that the two men were responsible for the death of Massachusetts Institute of Technology police officer and the shooting of an officer with the Massachusetts Bay Transportation Authority, the region’s transit authority. “We believe these are the same individuals that were responsible for the bombing on Monday at the Boston Marathon,” he said.
Several area colleges announced the cancellation of classes on Friday, including M.I.T., Harvard, Boston University, Boston College, Emerson College, Northeastern University and Suffolk University. Officials said the two men were from Chechnya, a long-disputed, predominantly Muslim territory in southern Russia that fought two bloody wars in the 1990s against Russian authorities.
“This situation is grave, we are here to protect public safety,” said Col. Tim Alben of the Massachusetts State Police. The family lived briefly in Makhachkala, the capital of the Dagestan region, near Chechnya, before moving to the United States, said a school administrator there. Irina V. Bandurina, secretary to the director of School No. 1, said the Tsarnaev family left Dagestan for the United States in 2002 after living there for about a year. She said the family — parents, two boys and two girls — had lived in the Central Asian nation of Kyrgyzstan previously.
“We believe these are the same individuals that were responsible for the bombing on Monday at the Boston Marathon,” Mr. Alben said. “We believe that they’re responsible for the death of an MIT police officer and the shooting of an MBTA officer.” Both brothers have substantial presence on social media. On Vkontakte, Russia’s most popular social media platform, the younger brother, Dzhokhar, describes his worldview as “Islam” and, asked to identify “the main thing in life,” answers “career and money.” He lists a series of affinity groups relating to Chechnya, and lists a verse from the Koran, “Do good, because Allah loves those who do good.”
In the course of the chase, the suspects shot and killed a campus police officer at the Massachusetts Institute of Technology and severely wounded a transit police officer, police said. The authorities were investigating whether the suspect who was killed had an improvised explosive device strapped to his body, two law enforcement officials said. The older brother left a record on YouTube of his favorite clips, which included Russian rap videos, as well as testimonial from a young ethnic Russian man titled “How I accepted Islam and became a Shiite,” a clip titled “Seven Steps to Successful Prayer.”
Edward Davis, the Boston Police Commissioner, told reporters early Friday morning that the two men involved in the chase were the suspects identified Thursday by the F.B.I. as responsible for setting the explosives at Monday’s marathon that killed three people and injured more than 170 others. Early Friday, a virtual army of heavily armed law enforcement officers was still going through houses in Watertown, outside of Boston, one by one in a search for the second suspect. The police had blocked off a 20-block residential area and urged residents emphatically to stay inside their homes and not answer their doors.
He also said that one of the suspects, wearing the black hat in the F.B.I. photos, was dead and that the other suspect, in the white hat, was still on the loose. The Boston police commissioner, Ed Davis, said: “We believe this to be a man who’s come here to kill people, and we need to get him in custody.”

“We are concerned about securing that area and making sure that this individual is taken into custody,” Mr. Davis said. “We believe this to be a terrorist. We believe this to be a man who’s come here to kill people, and we need to get him in custody.”
With gunfire ricocheting around the tranquil neighborhood, residents were later told to go into their basements and stay away from windows.With gunfire ricocheting around the tranquil neighborhood, residents were later told to go into their basements and stay away from windows.

A Watertown resident, Andrew Kitzenberg, 29, said he looked out his third-floor window to see two young men of slight build in jackets engaged in “constant gunfire” with police officers. A police SUV “drove towards the shooters,” he said, and was shot at until it was severely damaged. It rolled out of control, Mr. Kitzenberg said, and crashed into two cars in his driveway.

“They lit it, still in the middle of the gunfire, and threw it. But it went 20 yards at most.” It exploded, he said, and Tamerlan Tsarnaev ran toward the gathered police officers.
